1 I ATTACHMENT FOR HAIR GLIPPERS.

Application filed January 7 1922. Serial No. 527,631.

To all whom it may concern.

Be it known that I, GEORGE PosNIoK, a citizen of the United States ofAmerica, residing at Springfield, county of Hampden,

Commonwealth of Massachusetts, haveinvented certain new and usefulImprovements in Attachments for Hair Clippers, of which the following isa specification.

This inventionrelates to improvements in attachments for hair clippers.

,Aniobject of the invention is to provide an, attachment that is adaptedto be used on the ordinary clippers for automatically gaging orgradually varying the length of the hair which is being cut or trimmedso that it will present a smooth and finished appearance. In using theordinary clipper it is often times necessary to move the cutting oradvancing edge away from the head as the clipper is carried up the sideor back of the neck.

An object of the present invention is therefore to provide an attachmentwhich will automatically move the cutting edge of the clipper away fromthe head as the implement is moved forward during the cutting operation.In general it comprises a member adapted to be gradually moved outwardbeyond the lower plane of the cutting edge during the operation of thehandles. whereby the cutting edge is gradually moved away from the head;

A further ob 'ect is to provide means for rendering the deviceinoperative if desired during the cutting operations. The attachment ingeneral comprises a ratchet device which is operatedby the handles ofthe implement as they are moved toward and away from. each other. andsuitable connecting means between the ratchet device and the memberwhich engages the head and which serves to move the implement away fromthe head. a

A. further object is to provide means for setting or adjusting thedistance of the cutting edge from the head.

Referring to the drawings in detail:

1 and 2 designate the usual grip handles of the hair clipper which arepivotally connected together as indicated at 3; The operation of thesehandles moves thecutting plate 4 across the fixed or base plate 5 in theusual manner. 6 designates a U-shaped member havingthe downwardlyprojecting curved ends 6. This member is attached to the pivot 3 bymeans ofthe U-shaped memher 7 and the nut 8. The member 6'is clesignedto have a loose pivotal or swinging movement in the member'7. The member6 is provided with a downwardly projecting arm 8 to the lower endofwhich is connected the rod 9. This rod is bent and arranged.substantially parallel to the arm 1. On this rod is placed a coiledexpansion spring 10. 11 (see Fig. 4) indicates a box member which issecured to the handle 1 in any suitable way as shown by the screws at12. Located in the box member 11 is a pinion 13 which engages the rack1e and is attached to or forms a part of the rod 9. Secured to the shaftof the pinion 13 is a ratchet wheel 14. Attached to the arm 2 is abracket 15 having a downwardly extending bent portion 15. 16 indicates athreaded rod that passes loosely through the bent portion 15.. 17 is anut engaging the threaded portion of the rod 16 for adjusting the throwof the rod. Connected to the rod 16 is a leverarm 18 that is pivoted tothe box 11 at 19 also pivotally connected to the rod 16 at 16. The twopawls 20 and 21 are also pivotally connected to the rod 16 and lever arm13. These pawls are normally forced or moved away from each other andfrom" engage ment with the ratchet wheel14 as shown in Fig. 2. Thespring arms 22 and 23 are at tached to the boxll by means of the post 24around which these two pawls are coiled. In order to force or move thetwo pawls 20 and 21 into contact with the ratchet wheel 14, a lever 25is provided. This lever is pivoted to the box 11 at 26 and is formedwith a cut out portion 25. The ends 28 of this cut out portion, are whenthe lever is moved in the direction of the arrow 27 brought intoengagement with the spring arms 22 and 23 which forces the two pawls 20and 21. into contact with the teeth of the ratchet wheel 14. The lever25 is normally held in the full line or retracted position as indicatedin 1 by means of the spring plate 21'.

In Fig. 2 is shown the lever 25 moved into the dotted line position withthe edges 28 of the slot'25 engaging the spring arms 22 and 23 whichforces them together, as shown in dotted lines at 22 and 23. As theoperator moves the handles 1- and 2 the pawls 20 and 21 will engage theteeth of the ratchet wheel 14 moving it in the direction of the arrowand at the same time the pawl 21 on the lever 25 will engage one of theteeth of the wheel 14 and hold it against movement, which would resulton account of the expansive force o t the spr ng 10. The operation ofthis wheel turns or rotates the 131111011 13 which operates the rack 14,and in turn, operates the rod 9 in the direction of the arrow 9. Thismovement causes the lower end 6 of the member 6 to be moved downwardinto the dotted line position, whereby the cutting edge of the clipperis moved away from the head at a distance equal to the dotted line 29shown in Fig. 3. The end 16? of the rod 16 will be engaged by the innersurface of the handle 2 to move the rod 16 in the direction of the arrow16 It is to be understood that as the oper-.

inner end of the bracket arm 15 and serves to operate or push, the rod16in the oppositedirection as shown by the arrow 16 The ratchet wheel 14is thus operated in both the inward and outward directions of thehandles. In using the implement the operator must press or hold thelever 25 inward during the operation.

Referring to Fig. 5 which shows a modification, 30 designates a blockhaving a wedge shaped or tapered portion 30' at its forward end. Thisblock is mounted for sliding movement on the lower surface of the; plate5 and is pushed forward by the rod 9, which rod is connected to a lever31 that is pivoted to the implement at 32. A slotted connection 31 isprovided for the pin 32. i

Itis to be understood that the rod 9 is operated by means of the ratchetpawl a dovetail construction indicated at 30? in flexible hinges 34.Attached to the mem ber 33 is an arm 35 which arm is pivotally connectedto the sliding rod 36 at 36. This rod is mounted for movement inthecasing 37 and is normally held in a retracted position by means ofthe spring 38. The forward end of the rod is formed with a rack 39 whichengages the pinion 40. This pinion is operated by means of the ratchetwhee141 to which it is connected. 42 and 43designate two pawls which arepivotallyconnected to the opposite ends of the slidable-inember 4 forengaging the ratchet wheel 41, when the slidable member 4 is moved inopposite directions by the handles 1 and 2 as indicated by the arrows44. 45 designates a lever which is loosely pivoted on the post 46.Connected to this lever is a link 47 which is provided with notches 47"for holding it in an adjusted position.

Attached to and carried by the lever 45 are two arc-shaped pieces 48 and49 for the purpose of engaging the pawls 42 and 43 for holding them awayfrom engaging the teeth of the ratchet wheel 41 when itis not desired tohave them turn the wheels 40' and 41 and move thepiece 33 downward, asshown in the dotted line position. The pawls 42 and 43 are retained inthis inoperative position by means of the teeth 47. If it is desired toset the piece 33 in fixed position the link 47 is set to render thepawls inoperative. The operator now turns the set screw 50 which isformed with a plurality of elevations 51, 52,53, and 54 of difierentelevations. The elevated surfaces engage the pin 35 onthe rod 36whereby,

by means of the connection with the rod 35 the wedge shaped block 33 ismoved downward into the dotted line position as shown in Fig. 11.
